This is similar to work done by moral philosopher Alasdair MacIntyre, who attempts to show that because ethical language developed in the West in the context of a belief in a human telos—an end or goal—our inherited moral language, including terms such as good and bad, have functioned, and function, to evaluate the way in which certain behaviors facilitate the achievement of that telos. Even if oughts can be understood in relation to goals or needs, the greater challenge of ethical systems remains that of defining the nature and origins of the good, and in what sense one ought to pursue it.
